Ireland needs a new concept of defence following Russia's invasion of Ukraine and the destruction of the NordStream pipeline, Minister of State for European Affairs Thomas Byrne has said, adding that public opinion is not in favour of joining military alliances.
In an interview during a visit to France, Mr Byrne said that even though there is no doubt as to where Irish sympathies lie, public opinion is not ready for membership of the US-led NATO alliance.
"Russia invading Ukraine, totally against the UN charter, against the basic principles of territorial integrity, put the Irish people very firmly, instinctively on the side of right there," he said to news agency AFP..
"We're not neutral when it comes to an invasion like that, but we're neutral when it comes to joining a military alliance," he said.
Irish neutrality has sometimes caused consternation among its EU allies and elsewhere, but Mr Byrne said there were strong historic reasons for its stance.
"For a lot of our history, as an independent country, we were overshadowed in our own minds by the British attempt at conscription in 1918," which sparked angry protests from Irish nationalists and became a factor for the country's independence in 1922.
"I think that's partly where Irish neutrality comes from. Our neutrality has been characterised by non-membership of military alliances," he said.
'Have to defend ourselves'
The US-led 2003 invasion of Iraq - justified by false allegations of weapons of mass destruction being present in the country - added to Irish scepticism about NATO membership, he said.
"Public opinion is not in favour of Ireland joining military alliances. But also I think the public is seeing now that defence is different to offence," Mr Byrne said.
Ireland is currently concerned that submarine cables carrying trans-Atlantic internet traffic may be vulnerable to attack, which could cause havoc for European networks - a worry exacerbated by recent explosions destroying part of the Nord Stream pipelines for which Western governments have blamed sabotage.
"We've seen what happened at Nord Stream," Mr Byrne said.
"The submarine cables are partly in Irish waters. We have to defend our cables, we have to defend ourselves."
"In Ireland we probably need a new conception of what defence is, a new concept."
One way forward could be submitting the neutrality question to a Citizens Assembly, where members of the public examine important issues together with experts, preparing legislative change.
"The Taoiseach has said he may decide to hold a Citizens Assembly on that issue so that the public can think things through," Mr Byrne said.
Although there are currently no concrete plans for such a move, it could become "part of a wider debate on how to defend ourselves".
Previously non-aligned countries Sweden and Finland applied to join NATO in May in response to Russia's attack on Ukraine, and their accession protocols were signed in July.
Bosnia and Herzegovina, Georgia and Ukraine itself have also applied to join the alliance.
